Abstract

In 2018, the family Arenaviridae was expanded by inclusion of 1 new genus and 5 novel species. At the same time, the
recently established order Bunyavirales was expanded by 3 species. This article presents the updated taxonomy of the family
Arenaviridae and the order Bunyavirales as now accepted by the International Committee on Taxonomy of Viruses (ICTV)
and summarizes additional taxonomic proposals that may affect the order in the near future.
